OK, thanks to all volunteers. That's enough people for now so we don't need anyone else yet. I've had email addresses from about half of you so far; could those who haven't please email me at
steve@multipie.co.uk or send me a private message. There's no hurry at though.
The iPod Touch 5th Generation should be OK since it runs iOS 9. However, Apple tells me that iPod 4th Gen still runs iOS 8 so unfortunately we won't be able to test on those. (We're building the app to work on iOS 9 & 10; by the time we're ready to make CC for Apple public, iOS 10 will be launching, so we have to focus on supporting that instead of iOS 8.)
